4 Claims. 1

This invention relates to improvements in rail fasteners, and moreparticularly to fasteners of the anchoring spike type.

One object of the invention is to provide a rail anchoring spike, whichis self locking to efiectively hold the same clamped against the flangeof the usual rail.

A more specific object of the invention is to provide a fastener forrails in the form of a spike, driven into the tie which supports therail, extending through the usual tie plate, having the h'ead portionthereof provided with a laterally projecting arm at one side engagedover the flange of the rail to hold the rail in place, and a resilientlocking finger at the opposite side having hooked shouldered engagementwith the tie plate to lock the fastener against withdrawal from the tie.

Other objects of the invention will more clearly appear from thedescription and claims hereinafter following.

In the drawing forming a part of this specification, Figure 1 is atransverse, vertical sectional view through a rail member and anassociated tie plate and railroad tie, illustrating my improvements inconnection therewith, said section being taken on the line ll of Figure2. Figure 2 is a top plan view of Figure 1, partly broken away. Figure 3is a transverse, vertical sectional view through the rail member shownin Figure 1, said view being in a plane at one side of the tie, the tieand tie plate being shown in elevation and the spike member being shownas partly driven into the tie. Figure 4 is a view, similar to Figure 3,showing the spike member in another position. Figure 5 is a top planview of the tie plate employed in connection with my improvements, saidaway.

In said drawing, I0 indicates the usual rail member and II, thesupporting tie. The rail I [I is of the type commonly employed, havinglaterally projecting base flanges |2|2, the upper surfaces of which areinclined upwardly toward the web l3 of said rail.

In carrying out my invention, I provide broadly a tie plate A, and ananchoring spike B which clamps against the rail flange and hasshouldered engagement with the tie plate to lock the same to the plate.

The tie plate A is preferably of rectangular outline and is interposedbetween the base of the rail l0 and the tie member I I. As shown, theplate A is provided with an elongated, rectangular opening I 4 adaptedto accommodate the view being partly broken shank of the spike B. Theopening I4 is located to one side of the corresponding base flange l2 ofthe rail ID, as clearly shown in Figure 1, and has its length arrangedat right angles to the length of the rail. The wall at the end of theopening l4, remote from the rail flange, is downwardly beveled, asindicated at l5, and a relatively heavy, upstanding lug l6, formedintegral with said plate, is located adjacent said end of the openingand has a laterally projecting portion I! which overhangs the opening.The portion I! of the lug l6 presents a downwardly facing, flat abutmentshoulder l8, which serves as a stop for locking the spike B in position.The end face of said projecting portion is beveled oil to provide a camface I9.

The spike B is made of spring steel material and heat treated to provideresiliency. It comprises a shank portion 29 and a driving head member2!. The shank portion is preferably of rectangular cross section and hasits lower end pointed in the usual manner to facilitate driving the sameinto the tie. At one side thereof, the head member 2| is provided with alaterally extending, elongated arm 22 of the shape shown, engaging overthe corresponding bottom flange I2 of the rail l0. As most clearly shownin Figure l, the outer end portion of the arm 22 is downwardlythickened, as indicated at 23, said thickened portion presenting arounded or convex underneath face which bears on the flange l2 of therail. At the side of the spike B which is opposite the arm 22 of thehead, the latter is provided with a depending locking spring finger 24,which is formed integral with said head, The locking finger is slightlyoifset with respect to the shank of the spike and is inclined away fromsaid shank in downward direction, as shown in Figures 1 and 4. The lowerend of the finger 24 is formed into a hook portion 25, which is adaptedto lock beneath the projecting portion I! of the lug IS. The end of thehook portion 25 is beveled oil to provide a cam face 26 adapted tocooperate with the cam face l9 of the lug N5 of the tie plate. The topof the head 2| presents the usual flat driving face 21.

When the spike B has been driven home, as shown in Figure 1, with thearm 22 clamping the flange of the rail, the hook-25 of the finger- 24 isengaged beneath the projection I! of the lug l6 of the tie plate A, thuseffectively locking the spike against upward movement.

In applying my improved rail fastener, the spike B is driven into thetie through the opening M of the plate A, as clearly shown in Figure 3,by the .cam face 26 thereof riding over 5 the cam face I9 of the lug.When the spike is driven home, the hook portion 25 of the finger snapsbeneaththe projection 11 of the lug [6 to lock the spike againstremoval.

As will be evident, the spike B being made of mu resilient lockingfinger on the other side of said head, said finger having a hookedportion integral spring steel, the arm 22 is sufficiently resilientto.flex slightly in upward direction, thus easing: the upward pull on thespike, due to upward pressure exerted on the clamping arm: n by th erail flange, thereby preventing-thespikefrom 16 being loosened.
